<h2>Horizontal distance when projectile strikes water surface is 170 .02 feet</h2>
Step-by-step explanation:
The height is given by
We need to find when it strikes the water surface,
At water surface h = 0 feet
Substituting
Solving this quadratic equation to get x.
-32x² + 2500x + 500000 = 0
32x² - 2500x - 500000 = 0
x = 170 .02 feet or x = -91.90 feet
Negative x is not possible
Horizontal distance when projectile strikes water surface = 170 .02 feet
